In this paper an approach towards scalable group (many-tomany) communication across ATM networks is presented. Many network based applications rely on the concept of groups with dynamic membership. Todays ATM networks do not provide an adequate support for group communication as for example is available with IP multicast. In this document a hierarchical solution is described that adapts to the ...

Todays world relies heavily on spatial data to manage the natural and built environments. Monitoring and controlling the impact of human activities on the environment and the impact of natural environmental changes (including natural hazards) on the built environment is a major policy driver for many jurisdictions. The mitigation of natural hazards including tsunamis, earthquakes and landslides...

As business processes gain more importance in todays business environment, their unimpeded execution is crucial for a company’s success. Corporate decision makers are faced with a wide spectrum of potential risks on the one hand and a plenitude of security safeguards on the other hand. This paper gives an overview of a new approach for the elicitation of security requirements of business proces...

Electrical Machines areintegraland key equipments for engineering undergraduate, graduate, research scholars& for any processing industries. The modernization & automation of these machines are very much necessary in todays computer based environment. The available techniques for automation are very costly & unaffordable. This paper presents a new low cost, accurate & effective method for the a...

Experiments with wireless sensor networks have shown that unidirectional communication links are quite common. What is even more, they have also shown that the range of a unidirectional link can exceed that of a bidirectional one by far. Still, most of todays routing protocols do not use them, they only eliminate their implications. Those protocols that do use unidirectional links introduce a l...

Breast cancer is one of the most common cancer in the world. Early detection of cancers cause significantly reduce in morbidity rate and treatment costs. Mammography is a known effective diagnosis method of breast cancer. A way for mammography screening behavior identification is women's awareness evaluation for participating in mammography screening programs. Todays, intelligence systems could...

High-order filters, such as inductor-capacitor-inductor ( LCL) filter, have been popular in grid-tied power converters. Although featuring small size, LCL filters are not grid friendly due to inherent resonance, especially when a large number of converters parallel operation todays electric attain modularity, reliability, and redundancy advantages. Thus, this article reconsiders the low-order L...

In 1948, when Norbert Wiener published his path breaking work Cybernetics: Communication and Control in the Animal and the Machine, computer technology was in its infancy. Most computers that were needed to implement his ideas were of analog type, certainly in animals but also in machines. They were barely enough for executing simple algorithms, for example for extrapolating stationary time ser...

Strategic planning must be provided in libraries of all kinds for their designated positioning in todays knowledge society. The following concept points out, how a systematic review and assessment is enabled. On this fundament, positioning in the knowledge society, an ongoing optimization and sustainable enhancement of the library will be possible – both nationally and internationally seen. 1 D...
